SPRING-ROLLER ATTACHMENT FOR WINDOWS AND DOORS.

esasae.

T0 allwhom it may concern:

Be it known that I, AARON A. BURGNER, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented new and useful Improvements in, Spring-Roller Attachments for Windows and Doors, of which the following is a specification.

Thisinvention relates to a spring roller attachment for windows, doors, shutters and the like, andgthe object is to provide for mounting a roller or a plurality of rollers in the side or edge portion of a window sash, or in the window frame, for the purpose of facilitating the operation of the window and retaining the latter in its proper position in order to prevent rattling. The attachment is especially adapted for use on car windows and car shutters, but is also designed for use on sliding closures of various kinds.

A further object is to provide a window sash or the like with rollers mounted on one side of said sash in a stationary supporting device, and to provide on the opposite side of the sash a plurality of resiliently mounted rollers for insuring positive contact between the sash and the frame.

A still further object is to provide means for conducting cinders or the like from the recesses in which the rollers are mounted, in order to avoid the possibility of the rollers becoming obstructed and rendered useless for the purpose intended.

A still further object is to provide rotary means having a roughened or corrugated surface for contacting with a strip of metal mounted on the edge portion of the sash or on the window frame as the case may be.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of elements hereinafter described and claimed.

In the accompanying drawings:

Figure 1 shows the device, or a plurality of devices in elevation, as applied to a window sash, portions of the latter being broken away.

Fig. 2 is a further view in elevation, a fragment of the sash being shown in section.

Fig. 3 is an elevation taken at an angle 90 as compared with that shown in Fig. 2.

Fig. 4 is a view showing the rollers mounted in the window frame instead of in the Specification of LettersjPatent.

sash, portions of the frame being broken away and certain of the rollers being shown in full lines and others in dotted lines.

I will first describe that form of construction in which the rollers are mounted on the window sash and are designed to contact with the window amb or with-a metal strip mounted thereon. On one side of the sash I provide a plurality of rollers 10 each mounted within a bracket 12 and rotating upon a pin 14, the bracket being secured in position by means of screws or the like 15 and the roller being within a recess 16 formed in the side of the sash, said roller projecting to a slight extent from the edge of the sash. In the event that the frame is of metal no additional track or the like will be necessary, but if of wood I provide a separate strip of metal 17 shown in Fig. 1, which constitutes a track, and which is desirable in any wooden frame, and which is considered necessary in connection with a frame which has been worn by constant use prior to the time of applying the attachment herein described. It will be desirable in many instances to apply the device to the windows of cars which may have been in use for some years. In the event that the rollers are applied to the frame the metallic strip or track is applied to the edge of the sash as shown in Fig. 1, but of course this would not be necessary if the sash was formed of metal.

On the opposite side of the sash I mount a plurality of rollers on resilient devices in order that these rollers may at all times contactpositively with the window jamb and prevent the rattling of the sash, at the same time permitting the easy manipulation of the sash in raising or lowering the latter.

The flat spring member 25 is secured to the edge of the sash by means of suitable screws or the like, the edges of this spring being formed with projecting members designated 26 adapted to engage the edge portions of the sash. The spring carries a bracket portion 27 serving to mount a pin 28 forming an axle for the roller 29. A recess 30 is provided to receive the roller and its supporting bracket, said roller projecting however, to a slight extent from the edge of the sash under all conditions. The bracket is provided with an extension 31 which may contact with the wall 32 and limit the movement of the resiliently mounted devices.

Leading from recess 30 is a groove or channel 33 extending downwardly along the edge of the sash and terminating in outlet portions 34 for the purpose ,of permiting the escape of cinders which would otherwise accumulate within the recess and prevent the proper operation of the roller. This roller is formed with a roughened corrugated surface, the corrugations preferably extending diagonally across the face of the roller for the purpose of producing proper frictional contact with the window frame or the metallic strip carried thereby.

In Fig. 4 I have shown a plurality of rollers 40 mounted in stationary supporting devices secured to the window frame, these rollers contacting with the edge of the sash. On the opposite side of the frame are a plurality of resiliently mounted rollers 42 supported by means of springs similar to those already described and designated in this instance The operation of this form of the construction is substantially the same as of that previously described.

What is claimed is:

In a device of the class described, a window sash having a recessed edge portion, a bracket and a resilient device connected therewith for mounting the bracket, said bracket conforming to the shape of therecess and including an offset portion opposite the resilient device and engaging the edge of the sash for limiting the movement of the bracket and closing the adjacent'portion of the recess, and a roller mounted in the bracket for engaging a window frame, the sash having a restricted channel for the reception of the resilient element and the chan-- nel' having outlet portions for the discharge of dust laterally through the sash, and on the inner and outer sides thereof.

In testimony whereof I afiix my signature.
